Sierra Clark is a PhD student in the department of Epidemiology and Biostatistics in the School of Public Health and a member of the Global Environmental Health Research Group.

Sierra’s PhD research focuses on characterizing noise pollution in the city of Accra, Ghana and modelling the health impacts of noise reducing urban policy and planning scenarios. 

Prior to joining Imperial, Sierra completed a MSc in Epidemiology and a Bachelor of Arts in Geography at McGill University, Montreal.

During her MSc degree, Sierra was a National Geographic Young Explorer and a Mitacs Globalink International Intern, which jointly funded her research in rural China on household air pollution, cardiovascular health, and the effectiveness of improved cookstoves to reduce exposures and improve health. Sierra was also a research fellow at the department of Engineering at the University of Wisconsin in the Schauer Research Lab where she conducted chemical speciation analysis of air pollution samples. 

While an undergraduate student, Sierra was a member of the Indigenous Health Adaptation to Climate Change (IHACC) group where she conducted research on the factors impacting retention of mosquito nets among Indigenous Batwa in Uganda and qualitative field-work on the lived experience of acute gastrointestinal illness among the same population.
